Configuration Options

By default, the USB5533B configuration allows the device to operate as a standard USB hub when connected to a USB

host controller. The device also contains a number of configurable options which can be set through its user interfaces:

• One-Time Programmable (OTP) Memory (one time burn configuration)

• External SPI (only when using external SPI firmware)

• SMBus Slave Interface (controlled by SMBus host controller. Must be updated every time.)

Refer to Standard Interface Connections on page 13 for details on the SPI and SMBus interfaces.

SPI and OTP configuration can be created and applied through the Protouch tool. The following subsections detail to

various device parameters that can be configured via the Protouch tool.

5.2.1

CHARGING PORT ENABLE

This option enables, on a per-port basis, DFPs to become charging ports. If this is enabled on a port, it must be config-

ured as a per-port PWR/OCS control. Ganged OCS or PWR controls are not supported concurrently. The normal con-

figuration is to support the RapidCharge protocol. Refer to Section 5.2.17, "Port Power/OCS Control," on page 27 for

more information.

5.2.1.1

Apple Charging Mode

This option enables either Apple 1 Amp or Apple 2 Amp for the RapidCharge protocol charging mode when a port is

configured as a charging port and not enabled for Samsung Mode. This mode enables the selected Apple charging

mode to operate concurrently with BC1.2.

5.2.1.2

Samsung Charging Mode

This option enables the Samsung Charging mode on a port. If this is selected, the Apple Charging mode setting is

ignored and only the Samsung charging mode is supported on that port.

5.2.1.3

UCS1002 SMBus Interface Selection

USC1002 port power controllers are only supported if battery charging is enabled on that port. When BC is enabled,

there is an option to select the external signals (PRTCTLx/OCSx) that are used for the SMBus SDA/SCL signals. Only

Ports 1-4 signals can be used. This feature is supported on the “-6080” and newer devices.

5.2.2

USB VID

This field is the 16-bit USB Vendor ID reported by both USB 2.0 and USB 3.0 hubs.

5.2.3

USB2 PID

This field is the 16-bit USB Product ID reported by the USB 2.0 hub only.

5.2.4

USB3 PID

This field is the 16-bit USB Product ID reported by the USB 3.0 Hub only.

5.2.5

USB DID

This field is the 16-bit USB Device ID reported by both the USB 2.0 and USB 3.0 hubs.

5.2.6

USB NON-REMOVABLE SETTING

This is the per-port Non-Removable setting for both USB 2.0 and USB 3.0 hubs. If any ports are set as Non-Removable,

both the USB 2.0 and USB 3.0 hubs will be automatically set to report as Compound devices.

5.2.7

USB PORT DISABLES

This is the per-port setting used to disable ports for both USB 2.0 and USB 3.0 hubs.

5.2.8

USB SELF/BUS-POWERED

This setting is used to configure the USB2 and USB3 hubs to report as Self-Powered or Bus-Powered.

5.2.9

USB SYSTEM MAX POWER

This field is the maximum total system power on VBUS including non-Removable devices if permanently attached.
